ABSTRACT
Blunt trauma to the lower urinary tract is usually associated with pelvic fractures. The European Association of Urology (EAU) provides guidelines to diagnose and treat these injuries. The guidelines summarise the available evidence and provide recommendations on diagnosis and treatment of these patients. Therefore, these guidelines are important adjuncts to the urologist and emergency physician in the clinical decision-making. However, strict adherence to the guidelines is not always easy or possible because of concomitant injuries obscuring the clinical picture. This is illustrated by two case reports of concomitant injuries of the lower urinary tract (bladder with urethral injury). The clinical decisions will be discussed point by point and should serve as a practical teaching moment for the reader.
ABSTRACT
Male and female sexual dysfunctions encompass biological, psychological and interpersonal aspects. Premature ejaculation (PE) and female vaginal penetration difficulties (VPD) are problems that may concurrently impair the couple's sexual relationship. We have studied the correlation between PE and VPD in the female partner, in a cross-sectional study of 125 heterosexual couples (male age 35.01±10.63; female age 32.36±10.07). VPD included tampon insertion, gynecological examination, inserting self-finger or partner-finger and penile-vaginal intercourse. Female sexual function index (FSFI) and a validated PE questionnaire were used to measure the female sexual function and PE in their male partners. We found that female partners of men with anteportal ejaculation were found to experience significantly more VPDs, especially with regard to difficulties in penile penetration and tampon use. The intensity of pain in VPD was higher in females whose male partners presented anteportal ejaculation. No significant correlation was found between total male PE score and the total FSFI or separate domains of female sexual function. The results suggest that female VPD and male anteportal ejaculation are interrelated. Such severe couple sexual problems should be addressed in parallel. Further research is required to study the causation of PE and VPD.

The pivotal role of the medial preoptic area (MPOA) of the hypothalamus in the dopaminergic cerebral control of ejaculation has been investigated for years; nevertheless the function of different dopamine receptors subclasses and their exact interrelations merit additional research. One hundred nanograms of a preferential D(3) agonist 7-OH-DPAT (7-hydroxy-N,N-di-n-propylaminotetralin hydrobromide) was microinjected unilaterally into the MPOA of male rats anesthetized with urethane. An ejaculation-related response (bulbospongiosus muscles rhythmic contractions and/or seminal vesicle pressure increases and/or expulsion of a semen plug) was observed in 8 of 10 rats devoid of sexual stimuli, while a similar response was observed in only one rat administered with 10 ng of 7-OH-DPAT. The effect of 7-OH-DPAT 100 ng was mostly abolished by simultaneous MPOA microinjection of 300 ng of a preferential D(3) antagonist N-[(n-butyl-2-pyrrolidinyl) methyl]-1-methoxy-4-cyanonaphthalene-2-carboxamide tartrate (nafadotride). Our results support the hypothesis that supraspinal command of ejaculation is mediated by D(2)-like receptors, probably by D(3) receptors, in the MPOA, and draw attention to the idea of these receptors serving as a promising target for pharmacological treatment of human ejaculatory disorders.
